Make up the reaction equation: CH4 C2H2- CH2 = CHCl- polyvinyl chloride.

CH4 → C2H2 → CH2 = CHCl.
Under the influence of high temperature (16000C) it decomposes to acetylene and water.
2 CH4 = C2H2 + 3H2O.
Acetylene reacts with hydrochloric acid to form vinyl chloride.
C2H2 + HCl → CH2 = CHCl
Vinyl chloride enters into a polymerization reaction – the reaction of sequential addition of alkene molecules to each other due to the breaking of an unsaturated bond – forming polyvinyl chloride.
CH2 = CHCl + CH2 = CHCl + CH2 = CHCl +… .. → – CH2 – CHCl – CH2 – CHCl – CH2 – CHCl – +… → (-CH2 – CHCl -) n.
